Abstract
Described herein is a cost-effective and time-efficient method for producing UV- and HEVL-absorbing silicone hydrogel contact lenses capable of blocking ultra-violet ('UV') radiation and high-energy-violet light (HEVL) with wavelengths from 380 nm to 440 nm, thereby protecting eyes to some extent from damages caused by UV and HEVL radiation. This invention also provides UV- and HEVL-absorbing absorbing contact lenses made according to a method of the invention.
